carbotech pad choice
I've heard people talk about running XP10s in the front and XP8s in the rear. Any particular reason why? Is it a bias thing or is it just that they had problems with XP8 in the front?
I don't think it has anything to do with bias. The only reason I can think of is expected operating temps. The XP10 has a higher range of allowable operating temps. I'd look up the exact numbers, but I can't get my browser to work properly on the Carbotech site.
Straight from the Carbotech website:
XP10 (F=$158, R=$119)
- Max operating temp -> 1600F (no low range listed)
- Coefficient of friction -> well above 0.6 (their words)
XP8 (F=$147, R=$109)
- Operating temp range -> 250F to 1350F
- Coefficient of friction -> 0.58 to 0.6
So...it could be bias related I guess. XP8 rear set is only $10 cheaper than XP10, but may be more effective in a lower operating range.

I have used XP10/XP8s. The XP10 is just overkill in the rear. The pads will work best in their ideal temp range and the 10s in front and 8 in back get pretty close to that. If you put 10 in back, they will not get as hot as the 10s in front so the 8 in the rear work better. Also, the frict. coeff. is pretty high on the 10s so in the rear it can cause premature lockup.

Carbotech recommends a lesser pad in the back (to me anyway) so, there's no hint of the rear locking before the front. I believe they recommended XP10 F and Panther+ in the rear. I had no problems with that and no rear lockup issues even under braking heavy enough for the rear to get squirly.

panther plus work fine for guys starting out or if you run street tires.
I love the carbotech's, work great, and I can live with the dust (hawk dust eats through wheels)
